SPECIFICATION forming part of Letters Patent No. 405,948, dated June 25, 1889.

Application filed December 4, 1888- Serial No. 292,589. (No model.)

To all whom it may concern.-

Be it known that I, JEssE CooMBs, a citizen of the United States, residing at Green field, in the countyof Franklin and State of Massachusetts, have invented certain new and useful Improvements in Corn-Cultivators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Hy invention is an improvement in cultivators for corn, &c.; and it consists, generally speaking, of a cultivator arranged with a wheel-carriage and two sets of cultivator teeth or plows arranged to work on two sides of a row of plants and loosen the soil between the plants and about one-half the space on adj acent opposite sides.

My invention consists, also, in an arrangement of pulleys and chains, together with a hand-lever and ratchet device, by which the cultivator-frame may be adjusted to proper draft, or lifted entirely from the ground, at option of the driver.

My invention consists, also, in connecting the singletrees to the axle by chains, so that the entire strain of draft may be at the axle instead of upon the frame of the cultivator.

In the drawings illustrating my invention, Figure 1 is a plan or top View of the cultivator. Fig. 2 is a side elevation of the same. Fig. 3 is a rear elevation. Fig. 4 is a front elevation of same, and Fig. 5 is a detail.

Similar reference-letters indicate like parts in all of the figures.

Referring to the drawings, A is the axle of the cultivator, the main body of which may be of wood, but the journals for the wheels to be of iron, provided with shanks bolted to the body by means of clips b Z) and bolts 0 c. Bolted to the axle A are two long beams B B, two of the ends of which approach each other forward and the other two ends diverge rearward. Another long beam 0 is also secured to the axle A. On the front and rear ends of beams B B and O are bolted transverse beams D D, and pendent from these transverse beams D are slotted pendent legs E. WVheels of ordinary form are provided for the axle A, to complete the vehicle structure. I Chains F F F F are secured in pairs to the ends of the axle A, and to the ears of the clips which secure the body of the axle and their journals, and the pendent legs E E E E by suitable bolts and nuts.

Two metal cultivator-frames G G, of triangular form, put together in sections and properly riveted, areprovided with teeth or plows H, of suitable form, as many as may be required, secured to said frame G on either of the side bars of the same.

In front of the frames G,where the sidebars meet, and on the rear bars of the same are irons I, which rise, turn at right angles, and lodge in the slots of the respective legs E. These irons I are provided with hooks Z on their ends, and also as bearings for the outer faces of the slottedlegs E, anti-friction wheels K, properly journaled, are provided. The length of the axle A is such that when the wheels are on and the tooth-holding cultivator-frames are properly adjusted the said wheels will be in the middle of the said frames and in line with the slots of the pendentlegs E.

Upon the beams D D are fixed j ournal-bearings L L L L, which in pairs support shafts L L and fixed to said shafts are outer pulleys M M, and also pulleys M M To the outer pulleys on the shafts L L are fixed chains (Z (l, which connect with irons I by hooks Z Z.

To axle A, connected with bolts N of the legs E, are loops 0, to which are linked corresponding loops 1), to which are pivoted suitable singletrees.

The rear sets of chains F serve to brace the rear legs E, and the front sets F serve a similar purpose for the front legs E. The chains F, however, are designed more particularly for the purpose of confining the draft to the axle rather than to brace the axle and the cultivator-frame together.

Upon a shaft R, j ournaled between the beam C and one of the beams B, is a ratchet-wheel Q, fixed to pulley Q. A lever S, collared upon the shaft R, has a latch f looped to it, which latter is connected by a rod to a handlever pivoted to said lever S. The latch f,

acted upon by a spring g, is kept normallyin engagement with the teeth of the ratchetwheel Q. Pulleys M are fixed upon shafts L L andconnecting said pulleys M with pulley Q are chains h.

A spring-detent Uwith a foot-piece 7c is secured to the underside of the front transverse beams D, and 2. lug or offset Z secured to said detent, takes into the teeth of the ratchetwheel Q.

The cultivatonframes maybe lifted to regulate the draft of the cultivator-teeth or to lift said frames and teeth entirely from the ground in the following manner: The driver mounted upon a seat V reaches with his right hand the handle of the hand-lever S, his fingers being upon the thumb-lever T to throw the said hand-lever forward for a hold. He then releases the said thumb-lever, so that it may take onto the teeth of the ratchet-wheel. He now draws the hand-lever S toward himself, thus revolving the ratchet-wheel and pulley connected with it, which latter winds the chain h on itself, and through the shafts L L and pulleys M M and chains (1, connected with hooks of iron I, lifts the triangular teethcarrying frames to any required height. When the driver releases the hand-lever S, the spring-detent checks any tendency to back movement of the ratchet-wheel and secures the said frames toposition. The weight of the tooth-carrying frames, when the ratchetwheel is released, readily carries them toward or into the ground.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A triangular-shaped metallic cultivator! frame having teeth arranged upon its sides and the acute angle, and provided front and rear with irons I, terminatingin hooks Z, by which the said frame may be liftedfrom the ground, as set forth.

2. The cultivator-frame G, bars I secured thereto, provided with hooks Z and anti-friction wheels K, in combination with the vehicleframe, slotted legs E secured thereto, the pulley Q, ratchet Q, pulleys M M on shafts L L the chains h, secured to pulleys M and pulley Q, pulley M M on shafts L L the lever S, and spring-bolt T, whereby the cultivators may be lifted from the ground and so held, as and for the purpose specified.

3. The combination, with a cultivator-vehicle axle, plates or washers e and clips 19 secured thereto, of chains F, secured between the vehicle-axle and the slotted legs, and con- .nected forward by links to the-singletree,as

and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
